This is an SK epic 1.0 mob. I see him up on live servers and Phinigel, but not on Ragefire, Lockjaw, or Agnarr. Since these servers haven't hit GoD yet, I wonder if he's been mislabeled. He's not a bottleneck like Marl; I can't find anybody talking about him having a long respawn. I found this (inactive) ticket with links to his magelo etc.: https://dgcissuetracker.com/browse/EQ-1350
